Magnetoshperic Monitoring System deployed on Internet

这项研究方案是以前为测量和开发仪器而开展的研究的实用阶段，目的是利用因特网更好地管理和稳定快速地收集数据，该系统目前用于观测北极地区的磁场变化和极光图像。该方案的主要成果如下：1.未来几年将加强通过卫星链路或电话线从加拿大西部极光区和亚极光地区的站点收集磁场数据，这些站点与东京大学和阿拉斯加大学合作。2.在维多利亚附近的Rocky Point现场采集的磁场数据已经开始，现在正在通过移动电话连接到可从因特网访问的Unix计算机上连续传输。3.通过在WEB主页上显示极光图像和定期传输两个位置的图像文件，进行了极光图像的收集实验，LongYear by…更多En和NyAlesund，在斯皮茨卑尔根岛。我们经常丢失数据，即使是一张图片的数据速率(通常为10kb)标准一分钟，主要是因为岛上到挪威大陆之间的通信线路容量很窄。(4)与伊尔库茨克日地研究所合作，在Olkohn北端非常安静的地点尤祖里安装并运行了感应磁力仪的自动数据记录系统，尽管现在通常在会议上手工将数据传送给我们。(5)基于许可协议，使用加拿大大气环境局的网络系统作为S与日本通信研究实验室的合作项目，实现从中央极冠最偏远的地点埃尔斯默岛尤里卡的基于Internet的数据采集。我们的需求有相当多的解决方案，并且正在迅速变化，因此重新启动这类程序以跟上Internet的快速变化和扩展是非常重要的。较少

This research program was started as practical stage of a research previously made for surveying and developing instruments to utilize Internet for better management of and stable-speedy collection of data form a golobal network system presently operated for observing magnetic field variations and auroral images in the northern polar region.Topical upcomes of this program are as follows:1. remote data collection of magnetic field by satellite link or telephone line will be enhanced in coming years form sites in auroral zone and sub-auroral zone of the western Canada in cooperation of The University of Tokyo and University of Alaska. 2. Magnetic field data acquired at Rocky Point site nearby Victoria was started and is now ??ntinuously transferred by a cellular phone link to a Unix computer accessible from Internet. 3. Expeirments of collection of auroral images were made by displaying auroral images on a wed home page and by regular transfer of image files from two location, Longyearby … More en and NyAlesund, in the Spitsbergen Island. We had frequent data losses even for a data rate of a picture(typically 10kB)par one minute mainly due to a narrow capacity of communication line between the island to the main land of Norway. (4)an automatic data logging system for an induction magnetometer was installed and operated at Uzuri, the very quiet site in the northern end of the Olkohn is land in the Lake Bykal in collaboration with the Institute of Solar-Terrestrial in Irkutsk although data is now transferred to us by hand typically at conferences. (5)data collection based on Internet form Eureka, Ellesmer Island, the remotest site in the central polar cap, will be realized based on license agreement to use network system of Canadian Atmospheric Environment Service as s cooperation program with communication Research Laboratory of Japan. Quite many possibilities of solution to our requirement are available and are changing rapidly so it is very important to restart this kind program to catch up rapid changes and expansion of Internet.
